Title: Dynamic ram
Inventor: NAKAMURA MASAYUKI
IPC: H01L21/8242
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a step-up voltage-generating circuit and reduce the power consumption by a method wherein an oscillation pulse generated by an oscillation circuit is supplied to a charge pump circuit which generates a negative voltage. SOLUTION: If the selection levels of a word line and a shared switch MOS- FET are selected to be a power supply voltage VCC, a step-up voltage generating circuit can be eliminated. With this constitution, it is not necessary to add a process for, for instance, forming a MOS-FET whose withstanding voltage is improved and which is used in the step-up voltage generating circuit and a current consumed by the step-up voltage generating circuit can be eliminated, so that the power consumption can be reduced. Further, if the non-selection level of the word line is selected to be a negative voltage such as a substrate back-bias voltage, a reverse-bias voltage to a source potential is applied to the gate of an address selection MOS-FET and a leakage current by which the stored charge of an information storing capacitor is lost can be reduced.
